We get a lot of questions about which lens is best for me so we've got a few helpful. It totally comes down to personal preference but here are some helpful guidelines if you aren't quite sure.

50% Blocking Glasses
  • Ideal for mid day use when blue light has less of an affect
  • Allows more light through which means you get to see true colours
  • Blocks the 50% most harmful blue light
  • Look like regular prescrtiption glasses
99% Blocking Glasses

  • Tints everything yellow which can be a tad claustrophobic for some people
